Chinedu sat down to do his homework, which included 30 math problems. He solved 2 problems each minute. Let f(n) be the number of problems left for Chinedu to solve at the beginning at the n^th minute. f is a sequence. What kind of sequence is it?

Describe the 2 algebraic methods you can use to find the zeros of the function f(t)=-16t^2+400.
